Tarnos - La Digue Surf Forecast and Surf Report

Alright, let’s get into it. This is Rusty, and here’s the surf outlook for Tarnos - La Digue.

We’ve got a bit of a slow start here, mate. The next few days are looking pretty flat and sloppy. Thursday and Friday are a write-off with poor conditions. Best to leave the board in the car and grab a coffee. Saturday the 5th is where things start to wake up.

Saturday morning shows an uptick. We’re looking at clean 0.5 ft of NW swell, but it’s short period stuff at 8 seconds, so it won’t have much shape. The real standout is Saturday afternoon. That’s when a nice little pulse arrives: 4.9 ft of NW swell, and it’s a long period groundswell at 13 seconds. The wind goes glassy, and the combined energy hits 747 – that’s solid, moderate-to-strong wave energy. This window is the best on offer in the whole forecast. It’s not huge, but for a beginner-friendly spot like Tarnos, that’s a fun, clean size. Just bear in mind, with that long period, the sets might be a bit more spaced out, but it’ll make for a cleaner paddle out.

Sunday the 6th is a step down. The swell drops and the wind turns onshore, making things choppy. Monday and Tuesday are hit and miss – some clean morning windows but not a lot of power.

We then hit a dry spell from around the 11th through to the 15th of September. The swell is tiny and the conditions are ordinary at best. Weak energy readings in the 60–90 range tell the story. There are some mornings with light offshore or glassy wind, but the waves are just too small to get excited about.

The next real chance comes on Wednesday the 16th of September. A new NW groundswell shows up with 3.6 ft of swell at an 11-second period. The morning clean-up is solid, with an offshore breeze and combined energy of 383. That’s a good session for the intermediate crew. Then Thursday the 17th morning keeps that going with 3.6 ft of clean NNW swell and offshore wind.

Friday the 18th morning is totally glassy but the swell is back to 2.3 ft – a good reminder that this spot can be fickle in the long run.

Overall, Saturday afternoon the 5th is your magic session. It’s clean, has the most energy, and that long-period groundswell will wrap in nicely. The rest of the window is either too small or too windy. For a spot that’s fairly consistent like Tarnos, a few blank days are just part of the game. The water temp is 74.1°F – that’s running much warmer than normal, about 4.1°F above average, so no need for a steamer.

Stay patient and pick your windows.
